Guide for management of waste stabilisation pond systems in South Africa

Expanded Title:

The waste stabilisation ponds of the Free State have generally performed well for many years, effectively preventing environmental pollution and associated health impacts. Nevertheless, concerns were raised as to the current operational state of waste-stabilisation ponds of the Free State and their impact on both the natural environment and human health. Considering the above, a preliminary study of waste stabilisation ponds was initiated by the Free State DWAF office. Based on these findings, the Water Research Commission (WRC) decided to extend the study by conducting an in-depth study of selected waste stabilisation ponds systems in he Eastern Cape and Free State. The Free State and Eastern Cape systems assessed are within the Upper Orange Vaal catchment area. There are a few other systems assessed in the Eastern Cape that do not fall under this catchment area.
A waste stabilization pond assessment tool was designed to evaluate the different pond systems. The status quo report confirmed the poor operation and maintenance of many of the ponds in these 2 provinces which was ultimately linked to poor management practices. Based on these findings 2 guides and 1 manual was created to assist water professionals and specifically WSA's in improving the management and operation and maintenance of ponds. The research products are:
1) Guideline for Operations and Maintenance of a Waste Stabilization Pond System,
2) Guide for the Management of Waste Stabilization Pond Systems in South Africa, and
3) Manual for using Electronic Water Quality Management System (eWQMS) and Waste Stabilization Ponds Assessment Tool
